p.sendmessage not working

Hello im trying to fix my code a bit, but im a lil confused rn.

Maybe u could take a look and tell me whats wrong

Code:

import org.bukkit.event.EventHandler;
import org.bukkit.entity.Player;
import org.bukkit.plugin.Plugin;
import org.bukkit.Bukkit;
import org.bukkit.event.block.Action;
import de.max.SilentLobby.Core.Main;
import org.bukkit.Material;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.event.Listener;

public class InteractListener implements Listener{
    @EventHandler
    public void onClick(final PlayerInteractEvent e) {
        final Player p = e.getPlayer();
        if (e.getItem() != null && e.getItem().hasItemMeta() && e.getItem().getItemMeta().hasDisplayName()) {
            if (p.getItemInHand().getType() == Material.TNT) {
                if (p.getItemInHand().getItemMeta().getDisplayName().equals(Main.getInstance.mainItem) && p.hasPermission("Sl.use") && (e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK)) {
                    e.setCancelled(true);
                    p.teleport(Main.getInstance.filemanager.getSilentLocation());
                    p.sendMessage(String.valueOf(Main.getInstance.pr) + "You're now on the Silent-Lobby.");
                    Bukkit.getScheduler().scheduleSyncDelayedTask((Plugin)Main.getInstance, (Runnable)new InteractListener$1(p), 10L);
                }
            }else
                p.sendMessage(Main.getInstance.pr + "Not set a");
            {
        }
        }
        else if (e.getItem() != null && e.getItem().hasItemMeta() && e.getItem().getItemMeta().hasDisplayName()) {
                if (p.getItemInHand().getType() == Material.NETHER_STAR) {
                if (p.getItemInHand().getItemMeta().getDisplayName().equals(Main.getInstance.mainItemName) && p.hasPermission("Sl.use") && (e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK)) {
                e.setCancelled(true);
                p.teleport(Main.getInstance.filemanager.getSpawnLocation());
                p.sendMessage(String.valueOf(Main.getInstance.pr) + "You're now on the Lobby.");
                p.getInventory().setItem(Main.getInstance.ItemSlot - 1, Main.getInstance.methode.createItem(Material.TNT, 0, 1, Main.getInstance.ItemName));
                Bukkit.getScheduler().scheduleSyncDelayedTask((Plugin)Main.getInstance, (Runnable)new InteractListener$2(p), 10L);
                }
            }else
                p.sendMessage(Main.getInstance.pr + "Not set b");
            {
            }
        }    
    }
}
